Italian sculptor and architect, also called Maso del Bosco. He was the pupil of Andrea Ferrucci (1465-c. 1526), and later Michelangelo. As an architect he was the pupil of Antonio da Sangallo the Elder. After Michelangelo's drawing, he executed the recumbent figure of the pope on the tomb of Julius II (San Pietro in Vincoli, Rome). His group with St Anne, the Virgin and Child and the donor Pietro de Velasco (1544, Santa Maria di Monserrato, Rome) was influenced by similar groups by Andrea Sansovino and Francesco da Sangallo. //
